Product Overview
The Skyworks Si510/511 Crystal Oscillator (XO) utilizes advanced DSPLL technology to provide any frequency from 100 kHz to 250 MHz with a single fixed crystal. This IC-based approach offers enhanced reliability, improved mechanical robustness, and excellent stability. It features superior supply noise rejection, simplifying low jitter clock generation in noisy environments. Crystal ESR and DLD are individually production-tested for guaranteed performance. The Si510/511 is factory-configurable for various user specifications, including frequency, supply voltage, output format, and stability, with short lead times and no NRE charges.
